From http://hardware.slashdot.org/story/10/09/17/0247246/HDCP-Master-Key-Is-Legitimate-Blu-ray-Is-Cracked : MakeMKV rips most Blu-Rays very easily. If you want to re-encode with compression like x264, Handbrake will do it easily (though it takes about 6 hours at "20" quality on my i7 HTPC). The audio is a little tricky, but with MKVmerge you can just take the stream that MakeMKV gave you and mux it into the video stream Handbrake spat out. Subtitles are tougher because of the way they're done on Blu-Ray, but I find that opensubtitles.org usually has a perfectly-timed SRT file for my rips, most often from a guy called Shoocat. With newer codecs, the text is super-smooth and often looks better than the subtitles on the blu-ray. The only really hellacious problem I've had with moving my Blu-Ray...

Video taken with the Canon SD1200 camera comes in the AVI format, where the video is MJPEG and the audio is PCM. For some weird reason it doesn't play on my Windows XP box! The video is sluggish and the audio is often interrupted. But it works fine on my old Windows 2000 box. Since it's taking too much space anyway, I used mencoder to compress the video with XVID encoding and audio with MP3. This is the script. #!/usr/bin/perl $destdir = "C:/Documents and Se...
